An open running track. Sidewalks are hard on shoes and knees. Or work with schools to open them after hours and weekends. I just want to run without worrying about dog walkers, strollers or cars. Nature trails present the issue of tree roots. We have so many parks with tennis courts, baseball/softball fields and basketball courts. Runners want love too! Try putting tennis courts in the middle instead of a football field. The cushioned surface of a real track would be so much better than our less than perfect sidewalks.
